PROBLEM TO BE SOLVED: To efficiently execute accurate shape calculation by using an algebraic calculation method and a geometric calculation method together.;SOLUTION: When calculating shape data showing a desired shape in interactive environment, it is geometrically checked whether combination of plural drawing elements indicated as restriction conditions for defining the desired shape satisfies the restriction conditions for calculating the shape or not, patterns of a solution to be found are assorted according to relation between the restriction conditions and the assumed solution, and algebraic restriction conditions based on relation between the plural drawing elements and the solution are set in each the solution pattern (S1-S6). The solution is algebraically calculated on the basis of the geometric relation by simultaneously setting up the algebraic conditions in each the solution pattern, and accuracy of the calculated solution is geometrically checked (S7-S9).;COPYRIGHT: (C)2002,JPO
